The Lowdown
G’day, Rusty here. We’ve got a solid run of surf lined up at Jaconé over the next couple of weeks, but it’s not all smooth sailing—there’s a proper stretch of small, messy stuff in the second week you’ll want to dodge.
The pattern kicks off with a good, long pulse of southerly groundswell that rolls in Sunday the 9th and locks in through the middle of the following week. The water’s sitting at 73°F, which is a touch warmer than what’s typical for this time of year—nothing crazy, but you’ll notice it’s a little more comfortable.
Sunday morning the 9th is the first call. The swell is running 7 ft from the SSW with a period of 14 seconds—that’s a proper groundswell, long lines with solid energy (1556). A light NNW breeze is cross-offshore, so it’s clean. This is one of the true standouts of the whole window: excellent quality for experienced surfers. It’s a little strong for beginners at that size. This break is exposed to the swell, and with the direction coming in from the SSE optimum, you’re getting good shape.
Tuesday the 11th and Wednesday the 12th mornings are your next best bets. Tuesday has 8–8 ft southerly swell (1810–2278 energy), with a gentle ESE to E cross-off breeze holding it clean. Wednesday morning sees 7 ft southerly swell (1419) and a light ENE offshore—again, clean and punchy. This is where the consistency is at its best.
Thursday the 13th and Friday the 14th mornings are also very good: 6–7 ft southerly swell, offshore or light winds, clean faces. That Friday morning in particular has an ENE breeze at just 3 mph—almost glassy.
Then we hit a gap. From Friday afternoon the 14th through to about Wednesday the 19th, things get messy or drop off. Winds turn cross-shore or onshore, the swell gets shorter period and smaller. Tuesday the 18th is a write-off with onshore wind and weak, short-period junk. Wednesday the 19th sees tiny 3–3 ft east swell—barely surfable.
Thursday the 20th afternoon shows a bit of life again: 5 ft from the ENE, period 8 seconds (480 energy), clean enough, but it’s short-period stuff. Friday the 21st morning has a 6 ft SSW swell (374 energy) but with only 7 seconds—it’s soft and crumbly.
Saturday the 22nd morning is another standout for the second week: 4 ft SSE swell, period 10 seconds (747 energy), and glassy conditions with a 3 mph southerly breeze. That’s clean, lined up, and should be fun on a longboard or a fish. Lighter crowds possible, but it’s a quality window.
After that, Sunday the 23rd and Monday the 24th are mostly cross-onshore wind and rain—stay home or go for a paddle on the flat.
The best of the whole period is Sunday morning the 9th at Jaconé—that’s the one to circle. Second pick is Tuesday morning the 11th for power and consistency.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
